I have used Proteus and Ares and Eagle. Eagle is by far the winner...it can sometimes be a little daunting but its interface is ok, and it has a huge library, as well as support on the internet. I recently got a new job because someone saw one of my designs as well as an 'eagle3D' picture (a wonderful add-on madeby a genius). So that just goes to show that its a great piece of software..if I can do it...anyone can.
